摘要
目的 报道显微镫骨切除术方法改进后用于治疗薄板型镫骨型耳硬化症的经验。 方法 镫骨底板部分或全切除后 ,采用自体颞筋膜铺于窗龛表面而不是窗龛内封闭前庭窗 ,使前庭池增大 ,筋膜与豆状突间距离缩短 ,以减少术后移植物陷入压迫前庭的危险 ;利用镫骨头和前脚或后脚连接筋膜与豆状突 ,避免使用活塞型人工镫骨或钢丝筋膜垫可能造成的砧骨豆状突坏死。 结果 2 2例此类病例中 ,术后气骨导差 (5 0 0、10 0 0、2 0 0 0和 40 0 0Hz)在 10dB以内的有 2 1例 ,随访 1~ 3年无改变。 结论 改进的显微镫骨切术的手术方法操作简单、易于掌握 ,短中期疗效确切 。
Objective To report a new method for stapedectomy and its results Method Used temporal fascia to close oval window by putting the fascia on the surface of the oval niche instead of plugging it into the niche, which prevent the fascia from entering the vestibules and compressing the saccules; used the patients own stapes to connect the incus and the fascia to avoid incus erosion Results Of 22 cases undergone this modification of stapedectomy, closure of the air bone gap to within 10 dB (air bone gap average in 500, 1 000, 2 000, 4 000 Hz) were found in 21 cases and remained the same results in 1~3 years follow up Conclusion The modification of the stapedectomy procedure is a simple method with excellent results, being worth studying in the future
